UNITED STATES PATENT ALBERT EDWARD EAG-ER, O F PHILADELPHIA,PENNSYLVANIA.

BURNER.

To all 'whom t may concern:

Be it known that I, ALBERT E. EAGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBurners, of which the following is a specification.

One object of my invention is to provide a burner construction whichwill efiiciently burn liquid fuel, such for example as `light distillateoils, with a blue fiame which will not form a carbon deposit on deviceswhich are heated thereby. Thus my improved burner construction `isparticularly adapted for use in stoves, furnaces or other heatingdevices.

Another object is to so construct my invention that it can be quicklyand easily made and assembled and willbe of durable construction.

A still further object is to so construct my improved burner that it canbe quickly started in. operation and will be economical and safe whilein use.,

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is a front elevation of myimproved burner construction,

Fig. 2 is a top plan view of F ig. 1,

Fig.V 8 isa sectional plan view taken on the lineB-S yof Fig. 1, and

Fig. 4 is a sectional elevation taken on the line 4 4 ofFig. 2.

Referring to the drawings, 5 represents an elongated base plate having aperipheral flange 6. This base plate has two hollow domes 7 and 8 madeAintegral therewith. These domes respectively include depending cups 9and 10, said cups being open at their tops and being provided withperforations 11 atrtheir bottoms. The cups 9 and 10 are of smallerdiameter than the internal diameter of the domes 7 and 8 and therebyprovide spaces 12 and 13 respectively between the cups and the adjacentinner surfaces of the sides of the domes.` The tops of the domes 7 and 8are closed with the exception of slots 14and 15 which lead from Vthe up-Specication of Letters Patent.

Application led November 6, 1918. Serial No. 261,328.

per portions of the spaces 12 and 13 into the cups 9 and 10 above jetpipes 16 and 17.

bottoms of the cups 9 and 10 have air intake ports 20.

The jet pipes 16 and 17 are respectively connected by supply pipes 21and 22 to opposite ends of a chamber 23 provided by an elongated hollowflame-distributing and fuel-vaporizin casing 24. This casing 24 extendsentire y over both of the domes 7 and 8 and is supported above saiddomes by the supply pipes 21 and 22.

The bottom of the casing 24 is recessed as shown at 25, said recessbeing of greatest depth adjacent its Vmiddle and gradually becomingshallower at its edges, as clearly shown in Fig. 4. Furthermore, thisbottom of the casing 24 terminates in a peripheral flange 26. The top ofthe casing 24 `is provided with a central tapped opening 27 into whichis screwed the lower `end of a back pressure or equalizing reservoir 28.This reservoir is substantially spherical in shape as shown in theseveral views of drawing and has a contracted portion or neck 29 whichforms the joining portion of the reservoir with the casing as `abovedescribed.

The liquid fuel is supplied to the reservoir 28 by means of a pipe 30which enters said reservoir at a position a considerable distance belowthe top of the reservoir and slightly above the neck 29. By thisarrangement the reservoir provides an equalizing chamber which after theburner has started to heat causes a slight gas generation in thereservoir to start the vaporization of the liquid fuel.

The casing 24 is of greater length than the distance between the outerportions of the domes 7 and 8 and thereby serves to distribute the flameof the burner entirely around the peripheral flanged edge 26 of thecasing 24 to give an even distribution of heat, as wlll hereinafter bemore fully described.

Also, the top of each of the domes 7 and 8 has a bead 31 which providesa slight flare of the flame.

The space of cach of the cups 9 and 10 below the jet pipes is preferablyfilled with a material such as asbestos and to start the burner thismaterial is saturated with fuel and ignited; the interior of the cups 9and 10 being of greater diameter than the external diameter of the jetpipes and space is provided at each side of the jet pipes to permit theflame from the material 32 to pass upwardly heating the jet pipes andalso heating the casing 24 and reservoir 28. This initial heat causesthe liquid fuel to be vaporized sufficiently to produce enough vapor tostart the burner after which the burner will continue to operate and asthe heat increases the vaporization of the liquid fuel will beaccelerated until the burner is operating at its fullest capacity.

The particular construction of my improved burner produces an improvedresult. By having the jet holes 1S and 19 open into the combustionchambers 33 of the cups 9 and 10 below the tops of said cups and alsobelow the slots ll and 15 a substantially perfect combustion of thevapor with the air entering the combustion chambers through the slots 14and 15 is attained. Further than this by having the slots 14: and 15enter the combustion chambers in the position above noted the air isinitially heated and there is a direct upward pressure of the air to thetop of the domes 7 and 8 through the spaces 12 and 13 which produces adirect draft to forcibly enter the heated air into the combustionchambers at positions intersecting the jets of fuel vapor as they passupwardly out of the holes 18 and 19.

By having the reservoir 28 entering the casing 24 centrally and thesupply pipes leading off from the opposite ends of the casing both ofthe jet pipes receive substantially the sam@ amount of fuel under thesame pressure and an equal flame is produced. The fiame after leavingthe combustion chambers 33 impacts with the recessed surface 25 of thecasing 24; and distributes itself thereover and passes around theperipheral fiange 26 and thence upwardly. This action causes the heatingof the casing 2&1- to a high degree and thereby quickly vaporizes thefuel and provides a back pressure in the reservoir 28. Air also entersthe cups 9 and 10 through the perforationsv 11 and passes upwardly andmixes with the vapor and air from the slots 14 and 15.

The feed operates by gravity and is accelerated duc to the pressure setup as above described. A practically perfect combustion is secured andthe flame produced is extremely hot.

The sup-ply pipe 21 is preferably provided with a T-fitting 34C which isnormally closed by a plug 35 and the fitting 34; is in alinement withthe chamber 23.

The parts of my invention can be quickly assembled and can be readilycleaned internally and externally.

lfVhile I have described my invention as taking a particular form7 itwill be initierstood that the various parts of my invention may bechanged without departing from the spirit thereof, and hence I do notlimit myself to the precise construction set forth, but consider that Iam at liberty to make such changes and alterations as fairly come withinthe scope of the appended claims.
